大粒稻是一九七六年早季杂交的,在龙海县黎明大队农科所的协助下,经过三年五代的选育,获得一批千粒重40～50克,秆矮硬、叶短直,熟期早、中、迟多种类型的品系或株系.一九七八年晚季在黎明大队基点试种,表现出较高的增产潜力.其中,早熟的品系,千粒重40克,定名为“大粒早1号”,种植1.43亩,平均亩产1315.5斤;中熟的品系千粒重45克,第34号小区产量折合亩产1687斤.一九七九年早季拟将基本稳定的品系投入多点生产试验与较大面积示范,同时进行高产栽培试验,以测定其丰产性、适应性和抗逆性,探索高产栽培的规律.现在将培育大粒稻的设想、经过简报如下:
Large grain rice was hybridized in the early part of 1976. With the help of the Liming Brigade Agricultural Science Institute in Longhai County, after three generations of five generations of breeding, a batch of grain with a grain weight of 40-50 g, short stubble and short stamens , Early maturity, middle and late types of strains or lines in the late seventy-eighth season trial in the dawn brigade, showing a higher yield potential.Among them, precocious lines, grain weight 40 grams, naming For the “big grain as early as 1,” planted 1.43 acres, an average of 1315.5 pounds per mu; medium-cooked grain weight of 45 grams, No. 34 plot yield per mu 1687 kg. The first quarter of 1979 intended to be basically stable strains Put into multi-point production test and a large area demonstration, at the same time high-yielding cultivation test to determine its high yield, adaptability and resistance to explore the law of high-yield cultivation.Now we will foster the idea of large grain rice, after briefing as follows:
